A 90º degree angle is a right angle. Anything below is an acute angle and anything more than 90º is an obtuse angle.
-13+3b = -5-b
4b -13 = -5
4b = 8
b= 2
$145,714.28 because you divide 85,000 dollars by 7 then you multiply that answer by 12
Тhe third angle of the triangle = 90 - 60 = 30°
In a 30-60-90 triangle the side opposite the 30 degree angle is half the length of the hypotenuse, therefore


The answer is x = 12, y = 4√3
